What is the maximum load a HEB 200 column can support?

The capacity depends on three factors: unbraced length, steel grade, and code used. For a HEB 200 (cross-section area 78.1 cm², radius of gyration ry = 5.07 cm) in S275 steel, an unbraced length of 3 m gives a slenderness ratio KL/ry ≈ 59, which classifies as intermediate buckling. The design compressive strength per Eurocode 3 is approximately 1,850 kN for a 3 m column. For 4 m unbraced length it drops to ~1,600 kN. Shorter (2 m) gives ~2,050 kN. These are characteristic values before load factors. For combined compression + bending (beam-column), the capacity is further reduced by interaction equations. CalcSteel computes these checks automatically when you model the column and apply loads.
